Okies, In pure blue peter style here’s one I made earlier. This started life as a reverb, but I’ve changed the delays round a little so that now its a rather funky delay + even given you an impulse creation thing to test it out with.
If you wanted to make it variable, you could just put all the delays through the * object to make it more or less intense. You’ll still need to look at the tutorials on pluggo etc to get it working in ableton, but this’ll get you started. If you want more than just delay pitch shifting it couldnt hurt to look at gizmo~, however FFT is not easy to get into.
